SPOOL.

SPECIFICATION forming part of Letters Patent No. 370,121, datedseptember20, 1887.

Application filed December 22, 1884. Serial No. 150,010.

To all whom it may concern.-

Be it known that we JAMES W. CUMNOCK, and ENOOH SKILLINGS, both ofOhicopee, in the county of Hampden and State of Massachusetts, haveinvented a new and useful Improvement in Spools, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specification, inexplaining its nature, in which- Figure 1 is a perspective view of aspool containing our invention. Fig. 2 is a vertical central sectionthereof, and Fig. 3 illustrates a slight modification.

It is well known that the spools commonly used in certain classes ofmachinery usually used in the manufacture of cotton and woolen yarns arealmost invariably made of wood, and that, on account of the hard usageto which they are subjected, the edges of the heads become worn,abraded, and split, and that the spools, therefore, become valuelessbefore they are in other respects worn out. Various means have beenemployed to protect the edges of spoolheads from these results, but withindifferent success. The most common method has been to bind the edge ofthe spool-head with rawhide, or with a wood band, or with composition,but, so far as we are aware, these devices have not overcome thedifficulties-that is, they have not provided a good practical wearingspool. The principal trouble or diffieulty with the rawhide edge is thatit is quite subject to atmospheric influences and very easily extendsand expands when at all moist, so that however well it may be originallyfitted or secured to the edge of the spool there is no guarantee that itwill so continue. In fact, the probabilities are, and experience hasshown, that it will very shortly pueker up and become detached from thehead. The employment of a wooden protectingband does not overcome thedifliculty, because, while it may be an improvement upon the old form ofhead, still it is liable to the same defects which make the old formobjectionable. Moreover, it is (No model.)

quite expensive to make and apply. No composition, so far as we areaware, has yet been used which thoroughly and effectually protects theedge of spool-heads and wears well. It is therefore obvious from what wehave above stated that the material for properly covering and protectingthe edges of spool-heads must be strong and tenacious, must not fray orabrade easily, must not be subject to atmospheric influences or changes,and must, when applied to the edges of the spool, retain its originalshape thereon; and there is, so far as we know, but one material whichwill answer all the necessary requirements, and that is leather whichhas been so well seasoned that there is no liability of its stretchingor being subject to ordinary atmospheric conditions, and we have foundespecially desirable for this purpose the worn out leather clothing ofcards, old leather belting, and the like. We prefer to use the worn-outleather of cards. This we cut into strips of suitable width, thickness,and length to cover the exterior edges of the spool-heads, and we fastenthese strips thereto by fishglue, or with any other desirable unitingmaterial. We prefer that the joint between the two edges be anoverlapping one rather than a 7 5 each spool'head as slightly concave,to receive 85 the leather protecting-strip. We have learned byexperience that spools having their heads thus protected have long lifeand are all that can be desired.

We would state that ordinary green leather 0 cannot be used for thepurpose, because it is as liable to stretch as rawhide and issubstantially no better than it.

Having thus fully described our invention,

bis

we claim and desire to secure by Letters Patcards, all substantially asand for the purposes ent of the United Statesdescribed.
